I haven't played the game actively for awhile now and I couldn't find this answer or find a place to send them so....does anyone know if you can send IVs or GMTs to other players? I know you can send hbs but is that the only thing? I was considering doing a little contest/giveaway to try and help get me back into the game but then realized I didn't know if you could send IVs or GMTs which would change some of my prizes if I went that route. Thanks for any help!
